Study on Rotation Type Single Point Diamond Dressing

Effect on Dimensional Accuracy and Surface Roughness

Abstract

This paper presents a new dressing method, rotation type single point diamond dressing (RSPD dressing), in which a single point diamond dresser is rotated and fed to the direction of a wheel axis. The paper compares the dressing characteristics by this method with those of conventional single point diamond dressing (CSPD dressing). Main results obtained are as follows : (1) While the diamond edge form changes in CSPD dressing, it is almost maintained constant in RSPD dressing. (2) The wear of diamond edge in RSPD dressing is remarkably reduced compared with CSPD dressing. (3) In CSPD dressing, surface roughness changes as the wear of diamond edge. On the contrary, it is kept nearly constant in RSPD dressing because of the stability of the diamond edge form.
